Solid objects drawn in CAD software contain a volume. It is important for a 3D printer to recognize an object’s volume in order to apply material in the correct places.
Single-surfaced objects contain no volume and cannot be printed. Therefore, ensure any single-surfaced objects are given a specified thickness.
Occasionally, the inside or outside direction known as surface normals are displayed incorrectly and this can mean material is placed in the wrong locations. Most CAD programs have the ability to highlight normal directions and unify them which makes inside facing normals hidden from view.
This may cause errors during the print process. To correct these, fill any holes or gaps to make the object watertight.
|Widely used for rapid prototyping, this stereolithography format is best for creating meshed data without color information.
|Stands for Virtual Reality Modelling Language, this format support models with color and texture.
|Designed by ZCorporation, this format where possible should be used for data containing color and texture.
|Inition accepts this native format from Rhino users.
|Inition accepts this native format from SketchUp from version 7 and under.
|Commonly used in 3D Studio Max for parts containing color and texture.
|Widely accepted format that can carry color and texture information.
.ZCP & .PLY
|Commonly describes parts produced by 3D Scanners that contain color, texture and geometry.
